The alternative designation in parentheses is for information only and does not represent a different standard sieve size. Astm c astm normas fibra de vidrio. Record the approximate millivoltmeter reading. The volume should not exceed mL. If the solution above the settled solids is not pink colored, add more nitric acid wstm while stirring until a pink or reddish color persists, then add 10 additional drops of nitric atm and stir.

Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference. Privacy Policy Sensors Sitemap. If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. NOTE 4—Sampling tools may be cleaned with a brush, cloth, ethyl alcohol astmm, water rinse, or other method that will not contaminate the sample.

Originally approved in A superscript epsilon indicates an editorial change since the last revision or asm. Parte 1 de 2 Designation: Do not allow sample to boil more than a few c11152 See Note 6. A slurry that is only slightly acidic is sufficient. No lubricants shall be used during drilling. A digital readout is preferred but not required.

Note 1 — Sieve size is identified by its standard designation in Specification E Rinse the beaker and the filter paper twice with small portions of water. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Cover the beaker with a astmm glass and allow to stand for 1 to 2 minutes.

ASTM C / CM – 03 Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete

Such chloride will be detected by the use of this method. Submit the concrete mix design if the results will be expressed as Cl – percentage of cement. ASTM Volume Current edition approved Dec.

Some values have only SI units because the inch-pound equivalents are not used in practice. The titration may take place in a solution that contains a small amount of solid matter. Results Produced Chloride Cl – is determined and reported as weight percentage of the sample. These notes and footnotes shall not be considered as requirements of this standard.

Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce aatm high test results. Historical Version s – view previous versions of standard. Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure.

Clean all sampling tools prior to each sampling operation See Note 4.

ASTM C1152.C1152M – 04 – Acid-Soluble Chloride in Mortar and Concrete

However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in the very alkaline cement system. To prevent sample contamination, avoid contact of sample with hands and other sources of perspiration. In most cases, acid-soluble chloride is equivalent to total chloride.

It is the responsibility of the user of this standard to c11152 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The original beaker may be used See Note 7. Treatment with hydrogen f1152, as discussed in Test Methods C, is used to eliminate such interference.

Dissolve in water and dilute to exactly 1 L in a volumetric flask and mix thoroughly. However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become wstm or water-soluble after a period of exposure in the very alkaline cement system.

Make a blank determination using 75 mL of water in place of sample. The exact normality shall be calculated from the average of three determinations as follows: A number in parentheses indicates sstm year of last reapproval. Print and complete the following order form. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.
